Just ran through a small category relating to job placement that had been a bit neglected and had a few sites in unreviewed. Here is what happens when I go through the sites in date submission order (note the original submission dates):

1. 2000 - Site is not in English. It’s been submitted numerous times to numerous categories, and who knows how many it’s waiting in. Several editors have moved and/or rejected it over the last few years. Does not look like it has too many jobs. Moved to the right language for review again - but it will probably get deleted.
2. 17/Jun/2000 - Wrong category, which would have been obvious if the submitter has read the description. Moved to a more general category.
3. 18/May/2004 - Not in English and also the wrong category. Moved to my best guess about where it should go so someone who speaks German can review it.
4. 2004/2005 - Three sites that belong is a more specific sub-category, moved to the correct place, and I will review them there later. I could review and move them at the same time, but it’s less error prone to do it this way.
5. 08/May/2005 - Reviewed and published. Also since the site is in two other languages, sent two copies for other editors to review in those categories. It probably should get three listings.

So seven sites get reviewed ranging from several years ago to a couple of weeks ago. But the most recent one gets accepted, and the others get postponed. Hopefully this helps to explains the constant complaint - why don’t sites get reviewed in order.
